Technical Field

[0001] The utility model relates to the field of bearings, in particular to a high-strength and high-load-bearing bearing assembly. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or several raceways. The outer ring of the bearing is generally installed on the bearing housing. When overhauling and repairing the machine, it is often necessary to remove the bearing from the bearing housing. The installation of the outer ring of the bearing often adopts interference fit. However, if the outer ring is taken out and inserted multiple times, the connection between the outer ring and the bearing housing will become loose and slippery, reducing the toughness of the bearing, and thus affecting the use of the bearing.

[0003] Therefore, it is necessary to provide a new high-strength and high-load-bearing bearing assembly to solve the above technical problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a high-strength and high-load-bearing bearing assembly, which solves the problem that the connection between the outer ring and the bearing housing becomes loose and slippery when the existing outer ring of the bearing is taken out and inserted multiple times, reducing the toughness of the bearing and thus affecting the use of the bearing.

[0005] The high-strength and high-load-bearing bearing assembly provided by the utility model includes a bearing housing, an outer bearing ring and an inner bearing ring. A plurality of balls are arranged between the outer bearing ring and the inner bearing ring. Two pairs of load-bearing keys are symmetrically fixed on the outer wall of the outer bearing ring;

[0006] Two pairs of load-bearing key grooves are symmetrically formed on the inner wall of the bearing housing, and the load-bearing key grooves match the sizes of the load-bearing keys;

[0007] An arc-shaped positioning seat is arranged between each pair of the load-bearing keys. A positioning hole is formed on the surface of the arc-shaped positioning seat. An arc-shaped groove is formed on the bearing housing, and the arc-shaped groove matches the size of the arc-shaped positioning seat.

[0008] In a preferred embodiment, threaded holes are formed on both sides of the bearing housing. A limiting post is arranged on one side of the bearing housing. An external thread is arranged on the limiting post. One end of the limiting post penetrates through the threaded hole and extends into the positioning hole;

[0009] The limiting post is in threaded connection with the threaded hole.

[0010] In a preferred embodiment, a hexagonal block is fixed to the other end of the limiting post.

[0011] In a preferred embodiment, rubber sealing is adopted between the outer bearing ring and the inner bearing ring.

[0013] In a preferred embodiment, a leak-proof rubber ring is arranged at the liquid inlet.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. When installing this bearing, the staff only needs to put the bearing key on the outer ring of the bearing into the bearing key groove, and then use a wrench to screw one end of the limit post through the threaded hole into the positioning hole to complete the fixing work of the whole bearing. The operation is simple and convenient, and the disassembly is the same. At the same time, compared with the existing bearing that is press-fitted into the bearing housing, this bearing will not loosen or slip even after being disassembled many times, and has strong use stability;

[0016] 2. By arranging the bearing key and the bearing key groove, the bearing can be prevented from moving during use, greatly improving its anti-offset and load-bearing capacities, increasing the use strength, and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , wherein Figure 1 is the main structural perspective view of the high-strength and high-load-bearing bearing assembly provided by the utility model; Figure 1 ; Figure 2 is Figure 1Front view of the main structure; Figure 3 Stereoscopic view of the main structure of the high-strength and high-load-bearing bearing assembly provided by the present utility model Figure 2 .

[0023] In the specific implementation process, as Figures 1 - 3 shown, it includes a bearing seat 1, an outer bearing ring 2 and an inner bearing ring 3. A number of balls 4 are arranged between the outer bearing ring 2 and the inner bearing ring 3. Two pairs of load-bearing keys 5 are symmetrically fixed on the outer wall of the outer bearing ring 2. Two pairs of load-bearing key grooves 6 are symmetrically formed on the inner wall of the bearing seat 1. The load-bearing key grooves 6 are matched with the load-bearing keys 5 in size, ensuring that the load-bearing keys 5 can be completely placed inside the load-bearing key grooves 6, and the bearing will not shake during use.

[0024] An arc-shaped positioning seat 7 is arranged between each pair of load-bearing keys 5. A positioning hole 8 is formed on the surface of the arc-shaped positioning seat 7. An arc-shaped groove 9 is formed on the bearing seat 1. The arc-shaped groove 9 is matched with the arc-shaped positioning seat 7 in size. Threaded holes 10 are formed on both sides of the bearing seat 1. A limiting post 11 is arranged on one side of the bearing seat 1. An external thread 12 is arranged on the limiting post 11. One end of the limiting post 11 passes through the threaded hole 10 and extends into the positioning hole 8. The limiting post 11 is threadedly connected with the threaded hole 10. A hexagonal block 13 is fixed at the other end of the limiting post 11, which is convenient for the staff to rotate the limiting post 11 with a wrench. When installing this bearing, the staff only needs to put the load-bearing keys 5 on the outer bearing ring 2 into the load-bearing key grooves 6, and then use a wrench to screw one end of the limiting post 11 through the threaded hole 10 into the positioning hole 8 to complete the fixing work of the whole bearing, and the operation is simple and convenient.

[0025] A rubber seal is adopted between the outer bearing ring 2 and the inner bearing ring 3, and the dust-proof effect is better. A liquid inlet pipe 14 is connected and arranged at the top of the bearing seat 1. A liquid inlet 15 is formed at the top of the outer bearing ring 2. The liquid inlet pipe 14 is matched with the liquid inlet 15 in size. After the bearing is used for a period of time, the staff adds lubricating oil along the liquid inlet pipe 14 with a syringe, and the lubricating oil can enter the bearing through the liquid inlet 15. A leak-proof rubber ring is arranged at the liquid inlet 15 to avoid leakage of lubricating oil during filling and waste of materials.

[0026] Working principle of the present utility model: When installing this bearing, the staff only needs to put the load-bearing keys 5 on the outer bearing ring 2 into the load-bearing key grooves 6, and then use a wrench to screw one end of the limiting post 11 through the threaded hole 10 into the positioning hole 8 to complete the fixing work of the whole bearing, and the operation is simple and convenient. The disassembly is the same. At the same time, compared with the existing bearing installed in the bearing seat by interference fit, this bearing will not loosen or slip even after being disassembled many times, and has strong use stability;

[0027] By setting the load-bearing key 5 and the load-bearing key groove 6, the bearing can be prevented from moving during use, greatly improving its anti-offset and load-bearing capacities, increasing its service strength, and extending its service life.

[0028] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0029] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model.
